draftsCountAfter optionaldraftsCountBefore optionalSearch Gmail
Search the signed-in Gmail with the native query syntax (from:, to:, subject:, has:attachment, after:/before:, labels…) and return matching threads: threadId (feed it to get_thread / reply_to_email), sender, senderEmail, subject, snippet, date, unread, starred, hasAttachment. Results are threads rather than individual messages, which is Gmail's own search granularity, and only the first page of results is returned (up to 50).
Send Gmail email
Send an email from the signed-in Gmail account, with a plain-text body and an optional single file attachment.
Mark Gmail thread as unread
Mark a Gmail thread as unread by its hex threadId. Returns unread, threadId, the All Mail page it was found on, and already_unread. Acts from the All Mail list, scanning the first 4 pages (~200 newest threads). Safe to repeat: a thread that is already unread returns already_unread:true without clicking anything. Waits for Gmail to persist the change rather than returning on the optimistic row restyling, so the mail really is unread once the run ends.
